Can biting during sex cause a silicone implant to bust?

Thanks for the question. While the implants should not rupture, biting is probably not in your best interest. If it actually broke the skin it could lead to an infection which could jeopardize the implant. Best of Luck!

Bites and bruises will not affect the breast implant. Your partner would have to bite through the skin and breast tissue before damaging the implant.

No, unless there is much more aggressive “biting” than typical, sexual activity of the type that you describe should not damage the breast implants.  Best wishes.
